Kissing During The Dinner
"Neither my husband nor I are fans of the tradition of pounding on the tables or glassware for the bride and groom to kiss during dinner. We were both hungry, wanted to enjoy our dinner, were grossed out at the thought of kissing someone with a mouth full of food, and also are not big into public displays of affection. After the prayer and toasts at the reception before dinner, we announced that we would kiss once (and we did) and then asked our guests to refrain from doing this. A few non-compliant individuals still tried it, but we basically ignored them and they got the message that we truly weren’t going to do it."
Why? Because they don't want to follow every standard traditional thing?
If someone tells me that they don't understand some tradition a take them as an illiterate person. You don't need to follow, but understand? Just research it.
You can choose what you want.
